Something odd is happening inside Saturn

We may have found water on Mars, but something far stranger is happening inside Saturn.

Astronomers have noticed unusual movement in Saturn's rings. Here's the discovery in layman's terms: Generally, the ice and rocks that make up the rings travel outwards because of the gravitational pull -- but for some reason the debris seems to be moving towards the center of planet, leading scientists to believe something is moving deep within the gas giant. The astronomers speculate an object far beneath the surface is spinning at a speed of one rotation every seven hours.

Scientists hope by studying the movement of the rings, they'll be able to determine what's going on inside the planet.

"Even dropping a probe into the atmosphere would not necessarily help a lot, because the probe will only get down to a pressure of five or 10 atmospheres before it gets cooked or squashed,"the planetary scientist leading the analysis told Space.com. "We need to go much deeper to understand this."

Most scientists believed Saturn was pretty uniform, but they're learning it's actually a much more complicated planet.

Something odd is happening inside Saturn

First images captured of Pluto's moons by New Horizons probe in 2015.

Of all the planets NASA has explored, none have matched the dynamic complexity of our own. Earth is constantly changing, and NASA are working constantly to explore and understand the planet on scales from local to global. This time-lapse shows a composite for the eastern hemisphere from January 18 to July 25, 2014. Subtle changes in the snow and vegetation cover of the land vie for attention with a dynamic, swirling layer of clouds that are constantly present and constantly moving.

"Hubble Sees Flickering Light Display on Saturn - Astronomers using the Hubble Space Telescope have captured new images of the dancing auroral lights at Saturn’s north pole. Taken from Hubble’s perspective in orbit around the Earth, these images provide a detailed look at Saturn’s stormy aurorae — revealing previously unseen dynamics in the choreography of the auroral glow. The cause of the changing patterns in Saturn's aurorae is an ongoing mystery in planetary science. These ultraviolet images, taken by Hubble’s super-sensitive Advanced Camera for Surveys, add new insight by capturing moments when Saturn’s magnetic field is affected by bursts of particles streaming out from the sun."

"It's a small world! The phrase "encircling the Earth" has a double entendre flavor to it in this picture showing all six Expedition 39 crew members in the Kibo module around a globe while actually orbiting the "real thing" aboard the International Space Station. Clockwise from his position are Alexander Skvortsov and Mikhail Tyurin of Russia's Federal Space Agency (Roscosmos), Steve Swanson and Rick Mastracchio of NASA and Oleg Artemyev of Roscosmos."

"The sun emitted a significant solar flare, peaking at 7:42 a.m. EDT on June 10, 2014. NASA's Solar Dynamics Observatory – which typically observes the entire sun 24 hours a day -- captured images of the flare. It is seen bursting off the left limb of the sun in this image captured by SDO and is shown in a blend of two wavelengths of light: 171 and 131 angstroms, colorized in gold and red, respectively."

"Here's what happens when galaxies collide - as seen by our Chandra X-Ray Observatory: M51 is a spiral galaxy, about 30 million light years away, that is in the process of merging with a smaller galaxy seen to its upper left. This image is part of a "quartet of galaxies" collaboration of professional and amateur astronomers that combines optical data from amateur telescopes with data from the archives of NASA missions."

"Eclipse! From open prairie land on the 1625-acre Johnson Space Center site, one of our photographers took this multi-frame composite image of the so-called "Blood Moon" lunar eclipse in the early hours of April 15. During these rare events, the full moon rapidly darkens and then glows red as it enters the Earth's shadow."

"On Earth Day this year, NASA asked people all around the world a simple question - "Where are you on Earth Right Now?"We asked people to answer the question on social media, with a selfie. The goal was to use each picture as a pixel in the creation of a "Global Selfie" - a mosaic image that would look like Earth appeared from space on Earth Day. The mosaic was made with 36,422 individual images that were posted to social media sites on or around Earth Day, April 22, 2014."
